Adjustable bed mattress retainer system

Abstract

A mattress retention system for adjustable beds employs a tubular fabric tension web attached with a restraining bar to a top surface of an element of an articulating support structure. The restraining bar is secured with brackets inset from a longitudinal edge and lateral edges of the articulating support structure element.

What is claimed is: 
     
       1. A mattress retention system for adjustable beds comprising:
 a tubular fabric tension web attached at an edge to a bottom surface of a mattress cover proximate a longitudinal edge to be restrained, said tension web extending across a center portion of an overall width of the mattress cover inset from the lateral edges, said tension web having a retaining bar received therethrough; and, 
 brackets on a support section of an articulating support structure to receive ends of the retaining bar, said brackets inset from the longitudinal edge. 
 
     
     
       2. The mattress retention system as defined in  claim 1  wherein the tubular fabric tension web is attached to the mattress cover proximate a surrounding zipper. 
     
     
       3. The mattress retention system as defined in  claim 2  wherein the tubular fabric tension web incorporates reinforced stitched zones. 
     
     
       4. The mattress retention system as defined in  claim 1  wherein the retaining bar is substantially C shaped. 
     
     
       5. The mattress retention system as defined in  claim 1  wherein the longitudinal edge is at the mattress foot. 
     
     
       6. The mattress retention system as defined in  claim 1  wherein the longitudinal edge is at the mattress head. 
     
     
       7. The mattress retention system as defined in  claim 1  wherein the mattress cover incorporates a reinforced fabric layer stitched into the mattress cover in an end region adjacent the edge of the cover for additional support. 
     
     
       8. An adjustable bed comprising:
 a support structure having at least one articulating element with a top surface, a longitudinal edge and lateral edges; 
 a mattress received on the support structure on the top surface of the articulating element and having adjacent longitudinal and lateral edges; 
 at least one tubular fabric tension web attached at an edge to a bottom surface of a mattress cover proximate a longitudinal edge to be restrained, said tension web extending across a center portion of an overall width of the mattress cover inset from the lateral edges, said tension web having a retaining bar received therethrough; and, 
 brackets on the top surface to receive ends of the retaining bar, said brackets inset from the edge to be restrained. 
 
     
     
       9. The mattress retention system as defined in  claim 8  wherein the tubular fabric tension web is attached to the mattress cover proximate a surrounding zipper. 
     
     
       10. The mattress retention system as defined in  claim 9  wherein the tubular fabric tension web incorporates reinforced stitched zones. 
     
     
       11. The mattress retention system as defined in  claim 8  wherein the retaining bar is substantially C shaped. 
     
     
       12. The mattress retention system as defined in  claim 8  wherein the longitudinal edge is at the mattress foot. 
     
     
       13. The mattress retention system as defined in  claim 8  wherein the longitudinal edge is at the mattress head.
